The bigger problem here is that branch costs are a property of a

even if we did know, maintaining such a list would be almost impossible).
True, but you still get a reasonable set of targets where the test
passes vs fails -- not all the targets have as many variants as ARM :-)
I'd certainly agree that covering all the subtargets and then keeping
those lists accurate sounds like a lot of make-work.
